Constan Jackson, a logger employed in the camp of the Oso Logging Co., sustained injuries Wednesday from which he died in the Arlington hospital the following day. A tree which he was assisting to fall, kicked backward and slid down the hill driving the unfortunate man before it and badly mangling his right leg, the shock of the injury ultimately causing death. Deceased was a Russian Finn, 35 or 40 years of age and has no relative in this country so far as is known. Burial occurred at this place yesterday, the logging company bearing expense.
